Hear me out before I get blasted. I recently switched from T-Mobile  (late March - early April this yr). I had a BlackBerry Curve, a leaked OS / official for Europe showed up on XDA's site giving details on loading, etc. I installed the leaked version of the OS, and ......it worked perfectly fine until I retired the BB for the HD2. Back to today, I'm willing to wait a short time (at least I hope it's soon) to receive the official OTA for the ThunderBolt. Why? I do not want any bugs to mess it up. Cap'n Obvious, but Android is very different from BB's OS.
